How many grams of protein should a person who weighs 210 lbs intake per day (using 0.8 g/kg)?

To determine the amount of protein a person should intake based on their weight, it's essential to convert the weight from pounds to kilograms, as the protein requirement is often expressed in grams per kilogram of body weight. The conversion factor is that 1 kilogram is approximately equal to 2.2 pounds.

For a person who weighs 210 lbs, the conversion to kilograms would be calculated as follows:

1. Convert pounds to kilograms:

( 210 \text{ lbs} \div 2.2 \text{ lbs/kg} \approx 95.45 \text{ kg} )

2. Next, to find the recommended daily intake of protein, multiply the weight in kilograms by the protein requirement of 0.8 grams per kilogram:

( 95.45 \text{ kg} \times 0.8 \text{ g/kg} \approx 76.36 \text{ g} )

Rounding this off gives a daily intake recommendation of approximately 76 grams of protein.

This calculation aligns with the scientific guidance that suggests a protein intake of 0.8 grams per kilogram of body weight for sedentary adults. Thus, this demonstrates the accuracy of selecting 76 grams as the correct answer.
